    摘要: The present invention relates to a method and apparatus for setting the transmission power of a terminal in a wireless communication system. Particularly, the initial transmission power by means of which the terminal transmits a signal via an uplink non-anchor carrier is determined by reflecting the transmission power by means of which the terminal has most recently transmitted a signal via an uplink anchor carrier and by reflecting the difference between channel environments of the uplink anchor carrier and the uplink non-anchor carrier, in a wireless communication system using a broadband formed by carrier aggregation. Consequently, the initial transmission power of the terminal is set as accurately as possible in the uplink non-anchor carrier, thereby preventing signal transmission delay and improving the reliability of received signals.

    摘要: In a wireless communication system a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that &; of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes˜results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.

    摘要: A control channel configuration method and apparatus is provided for supporting Inter-Cell Interference Coordination (ICIC) in an OFDM-based communication system. The control channel configuration method includes determining a Resource Block (RB) to be used for configuring control channels; configuring the control channels by mapping the control channels in a data channel region within the RB; and transmitting the configured control channels, wherein configuring the control channels includes mapping the control channels in units of Resource Element Groups (REGs) formed by binding one or more Resource Elements (REs) in a time domain-preferred allocation manner within the same RB.
